This visualization uses D3 v6 to render a scatter plot of Iris flower data, mapping petal length and width to the x and y axes while using sepal dimensions to determine each point’s rx and ry attributes, creating elliptical markers. A color scale distinguishes the three species (setosa, versicolor, virginica) as yellow, blue, and red. The SVG chart loads data from a CSV via `d3.csv`, scales positions with `scaleLinear` and `extent`, and adds axes using `axisLeft` and `axisBottom`. The dataset originates from a gist containing credit card usage records, though the code processes Iris measurements.
